JOHN WHITEHEAD, OSKALOOSA, IOWA;4

Letters Patent No. 60,305, dated December 4, 1866.

t SPECIFICATION.

T0 ALL WHOM I T MAY OONGERN:

Be it known that I, JOHN WniTEHEAD, of Oskaloosa, Mahasha oounty,and State of Iowa, have inventada t new and useful Improvement in Loom; and I do hereby declare that the following is a full, clear, and exact` v description thereof, which will enable others skilled in the. art to make4 and use thc same, reference being had to the accompanying drawing, forming part of this specification. Y

The nature of my invention consists in providing or-constructing plates and attaching them to the lathe of a loom so that they may be adjusted in such a manner asv to give a light or hard blow, (with the same power` applied,) so as to accommodate it to the kind of work that is required to be done. If the work is light the blow` or 'stroke will be light, and if the work is heavy the stroke will also be' heavy.`

By my invention striped or fancy'clo'th may be wovenby a child rapidly.'` t p To e'nable others skilled in the art to make and use myinveution Iiwill'proceed t9 describe its construction and operation. y t

Figure 1 is a frontxelevation of my improved loom, Figure 2 is a transverse sectional elevation taken i'rom the linez t i Letters of like name and kind refer to like parts in cachot' the gures. i

A represents a frame, made of wood or other nia'terial, and to which my improved loom is attached. B is C the breastlbeam, passing from postte post of the frame and secured thereto, and is located immediatclyin front of the operator while operating, and when inpsition upon the seat c. t D is the lathe, at the end of which are a. series of shuttle-boxes, y y, located in a fra e, o ne above the other, and so arranged that they may he raised f or lowered as desired by means of cords and lever E a a,vso that a number of shuttlesniay'bc used `at the same t time, each shuttle containing different colors of yarn., This series of shuttle-boxes is` m'ade to slideup and down t upon rods F F, and the boxes are suspended `to the cords a a, which are attached tojthclever` G is the t shuttle-board, which extends from side to side of the lathe and connects with the shuttle-boites art each side of the said lathe. 'H H `are the harness-frames, which are'suspended by cords I Lattached to what are commonly p termed jacks, and designated by the letter J J. K is the cloth-beam, around which thejcloth is wound or taken up as it'is woven. At the end of the'cloth4beam is a ratchet-wheel provided with atlevcr and `pawl and detent` t N. These are for the purposes of taking up the cloth and straining the warpsullicieutly forhweaving. is the t yarn or warp-beam, which is also provided 'with a ritchet-wheelP and pawl Qwhich is also used for the `purpose of letting o' the yarn which is represented in red lines, iig. 2.. R R are` the treadles,'vivhicl1` arc attached by a y joint to the bottom of the legs of the seat ortstool, and the other ends arei'suspendedlby 'a cord attached to the levers S S, as shown in dotted lines, iig.v 1. -The ends of Athese said levers S S are also attached `to cordsp'fl p The cross-beam of the latheis provided 'with an adjustable ilang'ed strap or plato b byligrg, which ts incorres- 1 pending notches in other plates, c e. The said plates c c are secured upon the top of the frame A. Theplates b b are made adjustable in order that the lay Vmay be set'further or nearer vto its axis of Intion or benringpointon the frame, so that the laymay .be made to beatup the weft or filling with more or lesszforce, owingto the quality ofthe cloth being uiamitactured. Heavy work requires a heavy, `andlght vwork a light stroke` CV v i is a post provided with a notch forithe purpose of retaining and guiding the directionof the lever. Thesaid t i post is attached to the lathe-beam wwaretwo springs attached to the two back postsof the frameA. .At`

the end of the said springs are attached cords that connect with the lathe for the purpose ofrelieving the lathe rfrom any surging, so that, the stroke may besofter, and to assist in drawing back' the lath the stroke. t

Having thus described my'invention, what I'claim as new, and desireto secure by LetterstPatent, is-

The combination of the adjustable flanged plates b b attached to the lay, and the notched plat to the top of' lthe loom-framing, as herein described and for the purpose set forth.
